Pyrotechnic cutout for switching off a load e.g. in motor vehicle, has an ignition circuit, an operating current insulated from connection pieces and thermal separation between the connection pieces.

摘要

An ignition circuit traversed by part of an operating current is insulated from connection pieces (3,4) in a pyrotechnic cutout (1). Thermal separation between the connection pieces and an ignition/connecting conductor (24) produces a safe accurate response from the cutout.
